PULSE MULTI-MODULAR INSTALLATION OF DRY POWDER FIRE FIGHTING Russian patent published in 2019 - IPC A62C3/00 

FIELD: fire safety.

SUBSTANCE: invention relates to counter-intelligence equipment of fire fighting, in particular to pulsed multi-modal installations of operational dry chemical fire fighting, and can be used both to extinguish and temporarily suppress of flame of fountain and spill of flammable liquid, and can also be used to eliminate the ignition of heavy vehicles. In a pulsed multi-module dry chemical fire fighting installation containing a supporting member in the form of a metal frame, made with the possibility of its mounting in a vertical and inclined position (from -6 to +15 degrees), the frame is rigidly connected with at least one horizontal crossbar, on the crossbar mounting units are installed, ensuring the landing of each module body with the orientation of the module axis relative to the plane of frame at an angle mainly from 0 degrees to 24 degrees up, the design is made with the possibility of rigid fixation of units on it for fixing body of each dry chemical fire fighting module with a vertical axial release with a gas generator inside, the case is filled with chemical powder, the outlet hole of the module is covered with an opening diaphragm, each module is additionally equipped with a guide nozzle mounted directly on module outlet hole after the diaphragm and directed at an angle of 85–95 degrees relative to the module axis, at the same time, length of the nozzle is 2–4 diameters of the module outlet hole, fastening units mounted on the crossbar, made with the possibility of additional horizontal turn of the module with ensuring fan direction of axes of powder jets while maintaining the free angle of their disclosure.

EFFECT: extinguishing the flame of flammable liquid fountain with the height of 8–13 m; extinguishing of the flame spill flammable liquid on the area not less than 36 sq m; remainder of the powder in the module after deployment, less than 10 %.
